SG3524N ST DC-DC Controllers

The SG3524N is a regulating pulse width modulator IC from STMicroelectronics in DIP-16 through-hole package, designed for DC-DC converter and switching power supply control with push-pull and single-ended topologies. For selection, verify supply voltage from 8V to 40V, oscillator frequency up to 300kHz, output current of 100mA, 5V reference voltage, and operating temperature from 0°C to +70°C. Features include under-voltage lockout, soft-start capability, double-pulse suppression logic, and totem-pole output stage. Ideal for DC-DC converters, switching power supplies, uninterruptible power supplies (UPS), battery chargers, and industrial power control systems requiring voltage-mode PWM control with 100mA output drive capability.
